Description

[Detailed Description of the Invention] The present invention relates to a lighting device, and particularly relates to an improvement of a hanging device for hanging a lighting device by a chain.

In general, this kind of hanging device has a hanging chain B1 branched into three branches at the lower end of one hanging chain A, as shown in FIGS. 1 and 2, for example. B2. The upper end of the hanging chain A is attached to the ceiling surface, and the branch chain B1. B2. The bottom chain of B3 is the device body C
The slits D and the supporting portions E between the slits D and D are respectively supported.

However, for example, the lowermost chain Bla, which also connects to the branch chain B1, has its hook piece spread out to facilitate the pulling operation to the support part E. There is a problem that if a slight shock or vibration is applied to C, it will easily come off.

Therefore, conventionally, by bending the hook piece of chain Bta inward as shown by the dotted line in the figure,
．． However, in the assembly process, it is troublesome to bend the chain Bla inward using pliers, etc.
This has the disadvantage that assembly workability is impaired.

In view of these points, the present invention provides a lighting device that has a simple configuration, can reliably prevent separation from the device body without deforming the branch chain, and can also improve assembly workability. Examples will be described below.

In FIGS. 3 to 5, reference numeral 1 denotes a lighting fixture, which is composed of, for example, a fixture body 2 and a shade placed on the fixture body 2.

For example, three support parts 4 each constituted by slits 3.3 are formed at the top of the instrument main body 2.

Reference numeral 5 denotes a hanging device made of a chain, and is composed of, for example, a hanging chain 6 and branch chains 71, 72, and 73 branched and supported at the lower end of the hanging chain 6.

The lowermost chain γ1a of the branch chain 11 is hooked and supported by the support portion 4 of the instrument body 2.

8 is a flexible tube, and branch chain 7
1.72.73 is attached so that at least the lowest chain is encircled.

In this way, the lowest chain 7t of the branch chain 71
In a state where a is supported by the support part 4 of the instrument main body 2,
Since the chain γla is completely surrounded by the tube 8, even if a considerable impact or vibration is applied to the instrument body 2 and the branch chain, the chain 7ta will never come off from the instrument body 2.

Moreover, since the tube 8 is attached to the branch chain 71 in advance, the 9 ridges [
After the operation, the chain 7ta can be easily surrounded by lowering it from the dotted line position shown in the figure to the solid line position.

For this reason, the assembly workability can be improved compared to the conventional structure in which one piece of timber of the chain 7ta is bent.

In particular, when the chain 71a is surrounding the tube 8
For example, if the upper end edge is brought into contact with or positioned under the third (or fifth or seventh) chain from the bottom, that chain will act as a stopper for the tube 8, thereby preventing the tube 8 from sliding up. can be prevented.

In addition, the present proposal is not limited only to the above-mentioned embodiments,
For example, the upper opening of the tube can be made smaller in diameter than the lower opening, as shown in FIG. 6, or the tube can be made thick enough to provide some margin for the branch chain.

As described above, according to the present invention, the simple structure eliminates the separation of the branch chain from the device body without deforming the branch chain, and improves the ease of assembly.
